Nursing Leadership and Management

1. Functional nursing has some advantages, which one is an EXCEPTION?

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.

2. What is the measure of the total amount of space occupied by an object?

Correct answer: d

Rationale: Volume is the measure of the total amount of space occupied by an object and is typically measured in cubic units such as cubic meters or liters.

3. Aromatic compounds

Correct answer: A

Rationale: The correct answer is A: 'Aromatic compounds contain a ring structure with alternating single and double bonds.' Aromatic compounds exhibit a special stability due to the delocalization of pi electrons within the ring, known as resonance. This resonance occurs because of the alternating single and double bonds in the ring structure, making them less reactive towards addition reactions compared to alkenes, which have only double bonds. This stability also makes aromatic compounds less likely to be easily broken down by water, as they are relatively inert in many chemical reactions. Therefore, aromatic compounds do contain pi (π) bonds due to the presence of the alternating single and double bonds in their ring structure.

4. Polymers are

Correct answer: A

Rationale: The correct answer is A: 'Large molecules formed by repeating units called monomers.' Polymers are macromolecules made up of repeating units called monomers, which are linked together through chemical bonds. This repetition results in long chains or networks of molecules, giving polymers their unique properties. Options B, C, and D are incorrect because polymers are not simple organic molecules with low boiling points, highly reactive compounds used in industrial processes, or insoluble solids with no definite structure. Understanding the basic definition of polymers helps us appreciate their wide range of applications in materials science, engineering, and everyday products.

5. Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?

Correct answer: C

Rationale: Rationale: - The imaginary unit, denoted as "i," is defined as the square root of -1. - Therefore, 5i can be expressed as 5 times the square root of -1, which is equivalent to 5√-1. - Option A, -5, is a real number and not an imaginary unit multiple. - Option B, i^5, is equal to i because i raised to any power that is a multiple of 4 results in 1, and i^5 is equivalent to i. - Option D, 1/5i, is the reciprocal of 5i and not equivalent to 5i.

6. Kidney stones are formed when:

Correct answer: B

Rationale: The correct answer is B: "Minerals crystallize in the urine." Kidney stones are formed when minerals in the urine combine and crystallize, forming solid masses. This process can occur due to various factors, such as high levels of calcium, oxalate, or uric acid in the urine. Options A and C are not directly related to the formation of kidney stones. Option D is incorrect because not all the statements are true; only minerals crystallizing in the urine lead to kidney stone formation.
